[QUOTE="tourettes, post: 672510, member: 10858"] With version 16 release I would like everyone who downloads it to do two tests and post the results (with at least a minimal system config info - audio card at least...). There still seems to be some issues with the A/V drifting. I haven't been able to reproduce that drifting on 15 / 16 with almost 100 hours of testing (The International, Astronaut Farmer, Serenity... few movies are just played too many times already). [b]Test 1. 1:1 material[/b] [list] [*] Play 25 (or 50) fps material on 50 Hz display [*] Check A/V sync in the beginning - this should be in sync, if not there is no point in continuing the test [*] Leave video to play for 1 hour [*] Check A/V sync - this should be still in sync, if not the drifting has been happening (make an aproximation how much the sync is off) [*] Take a screenshot of the ! stats and post it here [/list] [b]Test 2. non 1:1 material[/b] [list] [*] Play 23.976 (or any other non 1:1 / 1:2) fps material on 50 Hz display [*] Check A/V sync in the beginning - this should be in sync, if not there is no point in continuing the test [*] Leave video to play for 1 hour [*] Check A/V sync - this should be still in sync, if not the drifting has been happening (make an aproximation how much the sync is off) [*] Take a screenshot of the ! stats and post it here [/list] In any case report the findings. This is the only way we can currently progress since I (or davidf) cannot fix a issue that we dont know about - especially since we cannot reproduce the issue at all. [/QUOTE]
